HT™ Wall Systems AVL Systems HT™ Wall Treatments are decorative, lightweight acoustic wall panel systems for home theatre and media playback applications. These products achieve outstanding performance from their innovative design and construction, utilizing the newest advances in materials, CAD/CAM manufacturing, and acoustical technologies. AVL Systems HT™ Wall Products provide maximum attenuation of reflected sound while diffusing returned low-level energy. Designer and Custom Finishes Durable, Impact Resistant Class A Fire Rating Superior Acoustical Performance Easy to Install Reasonably Priced HT™ Wall Systems have many advanced features that provide fresh aesthetic appeal with higher levels of performance. Featuring acoustical substrates that are custom-formulated to AVL specifications using an advanced European process, HT™ Walls provide appealing decorative looks and outstanding acoustical performance at an affordable price. Core construction is of thermo-molded, medium density fiberglass to dampen resonance and resist impact, and will not resonate, warp, or separate. Optional 1/8" special laminate (HT 110, 160, 210) concealed under facing provides extreme impact resistance with the added benefit of increasing low frequency absorption. Finished products are supplied to sizes as specified, ready to install with supplied fasteners for easy mounting to existing substrates. Fire Performance Composite assemblies with standard finishes have achieved a Flame Spread Rating of less than 25 (Class A) per ASTM E 84.   Acoustical Performance (Absorption Coefficients) 125Hz 250Hz 500Hz 1KHz 2KHz 4KHz NRC HT™ 1000 .07 .45 .95 1.07 1.07 1.18 .90 HT™ 1100 .19 .54 .97 1.10 1.13 1.42 .95 HT™ 2000 .38 .96 1.16 1.16 1.11 1.28 1.10 HT™ 2100 .54 1.01 1.16 1.11 1.19 1.59 1.10   Products | Absorption | Diffusion | Reflection | Product Applications
